have polycystic ovaries. I have been receiving treatment at a doctor near where I live for a month. I tested with a stick and one line was dark and one was faint. The next day I tested again and there was only one line. I had an ultrasound and it showed no pregnancy but my endometrium was 14mm. So if I have an ultrasound and no pregnancy but an endometrium of 14mm, am I pregnant or not?

My period is 8 days late, I tested and saw 2 lines, one dark and one light. I went for an ultrasound and the doctor said the endometrium is thick but the gestational sac is not visible, the fetus may be implanting. So doctor, can you tell me if my period is late, the endometrium is thick but the gestational sac is not visible, does it mean I am pregnant? Thank you doctor.

The endometrium plays a very important role in conception and pregnancy in women. Every month, under the influence of female sex hormones, the endometrium thickens to prepare to receive a fertilized egg. If there is no fertilization, the endometrium will peel off and cause menstruation. However, in some cases, due to insufficient hormones or some other cause, the endometrium thickens and vice versa, making it difficult for the embryo to attach, leading to miscarriage. Let's learn more about what a thick endometrium is in the following article.
